Once the egg is fertilized, abnormal sperm morphology does not appear to influence blastocyst development or blastocyst morphology. [6] Even with severe teratozoospermia, microscopy can still detect the few sperm cells that have a "normal" morphology, allowing for optimal success rate.
It is the opposite of hypospermia, which is defined as a semen volume of less than 1.5 mL. Hyperspermia alone does not appear to influence sperm health. However, large volumes of ejaculate may have lower concentrations of sperm, leading to low fertility. [3] [1] In some cases, high semen volumes can be a symptom of male accessory gland ...
The sudden rise in calcium levels causes the flagellum to form deeper bends, propelling the sperm more forcefully through the viscous environment. Sperm hyperactivity is necessary for breaking through two physical barriers that protect the egg from fertilization. The second process in sperm activation is the acrosome reaction. This involves ...
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
Studies suggest that globozoospermia can be either total (100% round-headed spermatozoa without acrosomes) or partial (20-60% round acrosomeless spermatozoa with normal sperm also identified in the sperm count), [3] however it is unclear whether these two forms are variations on the same syndrome, or actually different syndromes.
Causes of complete asthenozoospermia include metabolic deficiencies, ultrastructural abnormalities of the sperm flagellum (see Primary ciliary dyskinesia) and necrozoospermia. [ 1 ] It decreases the sperm quality and is therefore one of the major causes of infertility or reduced fertility in men.
Semen is an important indicator of men’s overall well-being and can help raise potential issues early. What your semen says about your health Skip to main content
The most common cause of sperm granuloma in pediatric and adolescent patients is often attributed to tumor obstruction, injury, or infection to the area. [5] While sperm granuloma is considered a complication in most cases, it allows decompression of the vas deferens and epididymis at the vasectomy site.
